IKE-RE W. GIDDENS, OF SALEM, OREGON.

LSWLSZS.

Application filed January 27, 1819.

To all whoa/1 it may concern:

Be it known that I, Knnn W. GinnnNs, a citizen of the United States,residing at Salem, in the county of Marion and State of Oregon, haveinvented certain new and use ful Improvements in Clasps, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention relates to certain improvements in clasps and hasrelation more particularly to a device of this general characterespecially designed and adapted for use in connection with a ribbon rollor bolt, and it is an object of the invention to provide a novel. andimproved device of this general character which may be applied withconvenience and facility and which operates effectually to hold theribbon end and without the necessity of employing a pin, as nowgenerally employed.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved claspwhereby certain important advantages are attained and the devicerendered simpler, less expensive, and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the bet ter understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein Figure 1 is a View in elevation of a clasp constructedin accordance with an embodi ment of my invention;

Fig. 2 is a view in bottom plan of the clasp as herein disclosed;

Fig. 3 is a side elevation of the device as herein embodied; and

Fig. i is a view partly in top plan and partly in section of my improvedclasp, as herein disclosed, the line of section being takensubstantially on the line 4l of Fig. 3.

As disclosed in the accompanying drawings, my improved clasp comprisesthe jaws A and B each formed, preferably, of a metallic plate with thejaw A of a width greater than the jaw B and the jaw B positionedsubstantially midway of the jaw A. The jaw A is arcuate in form tosubstantially conform to the peripheral configuration of a ribbon rollor bolt, while the jaw B is flat.

Specification of Letters Patent.

Serial No. 273,356.

The outer marginal portion of the jaw B is provided with a rounded edge,as indicated at a, so that the same may readily penetrate between thelaminations or plies of the roll or bolt. Each of the jaws or plates Aand B at its rear marginal portion is provided with a rearwardlydirected extension 1 terminating in the elongated arm 2 substantiallyperpendicular thereto.

W hen the aws A and B are in assembled relation, the arms 1 and 2 aresubstantially in parallelism and extend in the same general direction.The inner portions of the arms 2, adjacent their junctions with theextensions 1, are provided with the inwardly directed and transverselyspaced ears 3, the ears of one arm overlying the ears of the second arm.Disposed through the overlying or overlapping ears 3 is a pin 4 wherebythe jaws A and B are connected for relative swinging movement.

The jaws A and B are constantly urged one toward the other through themedium of an expansible member E interposed between the outer or freeend portions of the arms 2. As herein disclosed the expansible member Ecomprises a substantially U-shaped spring member having one extremityanchored as at to the outer end portion of one of the aans 2, while theopposite end portion of said member is in contact with the second arm 2.

In. practice the member B is inserted between the plies or laminationsof a ribbon roll or bolt at a point adjacent the periphery of the roll,while the plate or jaw A is caused to contact with the ribbon end. Theaction of the expansible member E is such as to cause the jaws A and Bto effectively clamp the ribbon end so that the necessity of employing apin, as is now generally done, is eliminated.

From the foregoing description, it is thought to be obvious that a claspconstructed in accordance with my invention is particularly well adaptedfor use by reason of the convenience and facility with which it may beassembled and operated and it will also be obvious that my invention issusceptible of some change and modification, without departing from theprinciples and spirit thereof and for this reason I do not wish to heunderstood as limiting myself to the recise arrangement and formation ofI-CI the several parts herein shown in carrying out my invention inpractice except as here inafter claimed.

I claim 1. As a new article of manufacture, a ribbon clasp consisting oftwo plates in overlying relation, one of said plates being flat and theother arcuate, the flat plate being of a width less than the arcuateplate and positioned substantially central of the arcuate plate, armsextending from corresponding marginal portions of the plates andextending in the same general direction, means for pivotally connectingsaid arms whereby the plates are capable of relative swinging movement,and means coacting with the arms for constantly urging the plates onetoward the other.

2. As a new article of manufacture, a rib bon clasp consisting of twoplates in overlying relation, one of said plates being flat and theother arcuate, the flat plate being of a width less than the arcuateplate and positioned substantially central of the arouate plate, armsextending from corresponding marginal portions of the plates andextending in the same general direction, inwardly directed ears carriedby the arms adjacent the inner ends thereof, the ears of each arm beingtransversely spaced and overlying the ears of the second arm, a memberdisposed through said ears whereby the arms are pivotally connected andmaintained in spaced relation, said pivotal connection also permittingthe plates to have relative swinging movement, and an expansible membercoacting with the arms outwardly of the pivotal member for constantlyurging the plates one toward the other.

3. As a new article of manufacture, a ribbon clasp consisting of twoplates in overlying relation, one of said plates being fiat and theother arcuate, the flat plate being of a width less than the arcuateplate and positioned substantially central of the arcuate plate, armsextending substantially at right angles to corresponding marginalportions of the plates and extending in the same general direction,means for pivotally connecting said arms whereby the plates are capableof relative swinging movement, and means coacting with the arms forconstantly .1rging the plates one toward the other.

In testimony whereof I hereunto afliX my signature in the presence oftwo witnesses.
